Problem summary

APAR NUMBER: PJ40698
PRODUCT: z/TPF
FUNCTIONAL AREA: IPL
SHIPPED IN PUT: 10
ABSTRACT:
Catastrophic CTL-1 possible when ipling with an unmounted copy
module
PACKAGE CONTENTS:
Source Segments:
(C) base/ol/ib06.cpy
(C) base/ol/ib03.cpy
Object Only Binaries:
None.
Configuration Independent Binaries:
None.
Support Files:
None.
OTHER BINARIES TO BUILD: YES
(C) <sys>/obj/iplb.o
(C) <sys>/load/IPLB.so
COMMENTS:
A copy module mount status is not checked until much later in
restart. This is problematic since it is a bit late to properly
abort a copy or prevent the processor from joining the complex
with an unmounted module. In the event that copy reaches end of
job during this time and a module swap is performed, the
processor with an unmounted copy module will take a
catastrophic error.

Problem conclusion

SOLUTION:
Copy modules (target modules of ZMCPY ALL operations) will be
checked for mount status like real-time modules during roll
call in IPLB. A new warning message of IPLB0125W will be issued
if a copy module is found to not be mounted and a subsequent
message of IPLB0022A will prompt for whether IPL is to continue
as is done for message IPLB0121W.
COREQS: NO
None.
